Dual Monitor Arm for 32 Inch Screens

The Ergotron HX dual monitor arm mounts two displays up to 32 inches diagonal and 5 to 17.5 pounds each on a single desk clamp or grommet base. VESA 75x75mm and 100x100mm patterns are supported directly. The stand is new and finished in white.

Bundled Mounting Hardware and Movement Range

The package includes the arm, extension, hinged bow, two monitor pivots, handle, a two-piece desk clamp for surfaces 0.6 to 2.6 inches thick and a grommet mount. The hinged bow folds outward for screen sharing while each pivot adjusts rotation, pan and tilt independently. Lift reaches 11.5 inches for a maximum height of 20.6 inches above the desktop with 360 degrees of rotation and 75 degrees of tilt.

Weight Capacity per Monitor Decides Fit

Each monitor must weigh between 5 and 17.5 pounds; displays outside that range will not be supported safely by the spring mechanism. Buyers with heavier screens or single-monitor setups should look for a different mount.

Questions about this item

Does the gas-spring mechanism on the HX Dual Monitor Arm require periodic servicing?

The arm uses a sealed gas spring designed for the product's lifespan; no scheduled maintenance or fluid replacement is needed.

What limits how long I can keep both 32-inch monitors at the maximum 20.6-inch height?

The 11.5-inch lift range sets the ceiling; once the arm reaches full extension the monitors cannot rise further.

Will the arm drift or make noise after holding two 17.5-pound screens all day?

Extensive testing confirms the gas spring holds position without drift and operates silently under continuous load.
